3D printers will one day become common product-design and manufacturing devices.

But this isn’t a moonshot industry. The 3D-printing market will already be significant, and cross the 1 million-unit threshold, within the next couple of years. By 2018, 3D printer shipments will increase tenfold from current levels, according to data analyzed by BI Intelligence. The trends all point to a significant opportunity quickly coming into focus.

Prices are coming down:Gartner also estimates the majority (85%) of 3D printers shipped in 2018 will cost under $2,500, indicating that 3D printers will not be limited to large-scale businesses.

There’s a clear market opportunity: 3D printer manufacturers and suppliers of the physical printing materials, such as a specially made plastics, to end-users will drive billions in revenue. Gartner estimates that in 2018, 3D printing end-users will spend over $13 billion in 3D printers and 3D printing materials. Last year, the firm estimated that 3D printing users spent just over $1 billion in 3D printers and materials.

The 3D-printing trend will create a new generation of entrepreneurs who will purchase 3D printers to fuel start-ups, speed up innovation at established companies, and reduce manufacturing costs across many industries.

There are already online marketplaces where owners of 3D printers sell their services to businesses and individuals who want to create three-dimensional objects, including toys, tools, and molds.
